The metrics that got SaaS companies funded in 2021: top-line ARR growth, logo count, net new ARR, team size. The implicit message: grow fast, figure out efficiency later.
The 2026 investor conversation is different. Not because growth doesn't matter — it does, critically — but because growth without efficiency is no longer fundable at the multiples of 2021. The investors who got burned by high-growth low-efficiency companies in 2022-2023 are asking harder questions.
The efficiency era scorecard that sophisticated investors are using:
Burn Multiple: net burn divided by net new ARR. How many dollars are you spending for each dollar of new ARR you add? Under $1 is world-class. $1-1.50 is good. Above $2 requires a compelling explanation.
Rule of 40: ARR growth rate + EBITDA margin. The sum should be 40 or above. A company growing 60% with -20% EBITDA margin passes. A company growing 20% with 15% EBITDA passes. Both sum to 40.
CAC Payback: as discussed, by segment. Under 12 months for most go-to-markets, under 24 months for enterprise.
NRR: the most reliable signal of product-market fit in existing customers. Above 110% is strong. Above 120% is exceptional. Below 100% means you're losing revenue from the base.
Gross Margin Trend: not just the point-in-time margin but the direction. Improving margins indicate operational leverage. Declining margins may indicate AI cost increases, support scale issues, or professional services subsidy.
The scorecard tells a story. A company with high NRR, acceptable burn multiple, and improving margins is building a durable business even if top-line growth is moderate. A company with high growth, deteriorating margins, and high burn is borrowing from the future.
Build for the scorecard. It's the right discipline regardless of what the funding market is doing.
